Wayne G. Hammond and Christina Scull's book J.R.R. Tolkien, Artist
& Illustrator is found a draft of Thrór's map for The Hobbit
with a Noldorin phrase, discussed in note p. 150. It is quite easy to
understand, since the meaning of most words is known or easy to deduct; and
then it clearly appears that it is a version of the sentence written in runes
that gives the secret of the map. The translation found here is taken from the
first chapter of The Hobbit, where Gandalf interprets the runic
inscription.
